Center-pull fiber package and method for producing the package

Abstract

A center-pull fiber package is provided in which a fibrous material may be wound onto a core structure comprising a core element and an overwrap release paper. Upon removal of the center elements, an end of the fibrous material is exposed so that the package may be unwound by removing a predetermined length of the winding from the interior or center of the package.

What is claimed is: 
     
       1. Method for producing a center-pull package comprising the steps of: wrapping a core cylinder with a material release segment;   overlapping a first end of the segment with a second end of the segment;   winding a fibrous material around said segment;   removing the core cylinder from the package; and   removing the release material segment from the package so as to permit removal of the fibrous material starting from the interior of the package.   
     
     
       2. The method of claim 1, wherein said material release segment is silicone coated. 
     
     
       3. The method of claim 2, wherein only one side of said material release segment is silicone coated. 
     
     
       4. The method of claim 2, further comprising: positioning said material release segment during said wrapping step so that the silicone coating present thereon is in contact with said core cylinder.   
     
     
       5. The method of claim 1, wherein said fibrous material is an inorganic fibrous material. 
     
     
       6. The method of claim 1, wherein said fibrous material is a carbonaceous fibrous material which contains at least 90 percent carbon by weight. 
     
     
       7. The method of claim 6, wherein the carbon of said carbonaceous fibrous material is primarily amorphous in nature. 
     
     
       8. The method of claim 6, wherein the carbon of said carbonaceous fibrous material includes graphitic carbon. 
     
     
       9. The method of claim 1, wherein said fibrous material is an organic polymeric fibrous material. 
     
     
       10. The method of claim 9, wherein the organic polymeric fibrous material is selected from the group consisting of acrylic polymers, polyolefins, polyesters, polyamides, polybenzimidazoles, and cellulosics. 
     
     
       11. A center-pull package for dispensing a continuous length of a fibrous material comprising a core cylinder, a material release segment, and a winding of said fibrous material, said material release segment being wrapped around said core cylinder with a first end of said segment overlying a second end of said segment, and said winding of said fibrous material being applied around said material release segment. 
     
     
       12. The center-pull package of claim 11, wherein one side of said material release segment has a silicone coating. 
     
     
       13. The center-pull package of claim 12, wherein the silicone coated side is in contact with said core cylinder when said material release segment is wrapped around said core cylinder. 
     
     
       14. The center-pull package of claim 11, wherein said fibrous material is an inorganic fibrous material. 
     
     
       15. The center-pull fiber package of claim 11, wherein said fibrous material is a carbonaceous fibrous material which contains at least 90 percent carbon by weight. 
     
     
       16. The center-pull package of claim 14, wherein the carbon of said carbonaceous fibrous material is primarily amorphous in nature. 
     
     
       17. The center-pull fiber package of claim 14, wherein said carbon of said carbonaceous fibrous material includes graphitic carbon. 
     
     
       18. The center-pull package of claim 11, wherein said fibrous material is an organic polymeric fibrous material. 
     
     
       19. The center-pull package of claim 18 wherein the organic polymeric fibrous material is selected from the group consisting of acrylic polymers, polyolefins, polyesters, polyamides, polybenzimidazoles, and cellulosics. 
     
     
       20. A center-pull package for dispensing a continuous length of a fibrous material comprising a core cylinder, a material release segment, and a predetermined length of said fibrous material wound in a plurality of overlying wraps around said material release segment, said predetermined length defined by a first end and a second end, said package produced by a process including: wrapping said core cylinder with said material release segment so that one end of said material release segment overlaps an opposite end of said material release segment;   winding said predetermined length of fibrous material around said material release segment starting with said first end;   removing the core cylinder from said package; and   removing the material release segment from said package so as to permit removal of the fibrous material starting with said first end.   
     
     
       21. The center-pull package of claim 20, wherein said material release segment is silicone coated. 
     
     
       22. The center-pull package of claim 21, wherein only one side of said material release segment is silicone coated. 
     
     
       23. The center-pull package of claim 22, wherein during said wrapping step said material release segment is positioned so that the silicone coating present thereon is in contact with said core cylinder. 
     
     
       24. The center-pull package of claim 20, wherein said fibrous material is an inorganic fibrous material. 
     
     
       25. The center-pull package of claim 20, wherein said fibrous material is a carbonaceous fibrous material which contains at least 90 percent carbon by weight. 
     
     
       26. The center-pull package of claim 25, wherein the carbon of said carbonaceous fibrous material is primarily amorphous in nature. 
     
     
       27. The center-pull package of claim 25, wherein the carbon of carbonaceous fibrous material includes graphitic carbon. 
     
     
       28. The center-pull package of claim 20, wherein said fibrous material is an organic polymeric fibrous material. 
     
     
       29. The center-pull package of claim 28, wherein said organic polymeric fibrous material is selected from the group consisting of acrylic polymers, polyolefins, polyesters, polyamides, polybenzimidazoles, and cellulosics.
